CANNES, France (AP) — A month before Kevin Costner puts the first installment of his multi-chapter Western “Horizon: An American Saga” into theaters, the actor-director came to the Cannes Film Festival to unveil his self-financed passion project.

“Two of my boys are out fishing right now,” Costner said with a grin in an interview at the Carlton Hotel. “And the three girls found their way onto a boat. So dad’s in here, stumping for his movie.”

The movie is actually two, or if Costner has his way, four. “Horizon: Chapter One,” which runs three hours, will be released by Warner Bros. in theaters June 28. “Chapter Two” follows August 16. Costner has scripts ready for parts three and four.

It’s only the fourth time Costner, 69, has directed, following 1990’s “Dances With Wolves,” 1997’s “The Postman” and 2003’s “Open Range.” But when he has, Costner has usually done it with a clear-eyed passion for storytelling and character. That’s on display in the wide-ranging epic “Horizon,” with a cast including Sienna Miller, Abbey Lee, Sam Worthington and Costner.
